Analysis of Control Strategy for AVC in Hydropower Station

doi:10.11985/2017.08.008

Abstract

Abstract:

Voltage is an important indicator of power quality. Automatic voltage control (AVC) to the busbar voltage of the system qualified for the restraint conditions, Reactive power and voltage optimization, distributed to the equipment control command of the adjustment process. Hydropower plant AVC is in accordance with the predetermined strategy to automatically control the power plant bus voltage or the whole plant reactive power, Adjusting the reactive power of the bus voltage stability in a reliable range. The AVC setting way, control mode, reactive power distribution, safety and precautions control strategies of hydropower plant are analyzed, including system status, operation mode, and unit vibration. Making AVC a reasonable control strategy, not only to meet the requirements of the system, but also to ensure the safe and reliable operation of hydropower equipment.

Key words: Hydropower station, automatic voltage control (AVC), control strategy
